I ordered a 6 disc Nav unit that came from a Lincoln MKX. That means it has Sync enabled. I took a Sync module from an 08 Fusion. I took the fist part of the sync harness but could not tear whole dash apart. Does that thing eventually go into the speaker wire set? Anyone have a Sync diagram?

 

Anyone? Does it basically splice in with the speaker wires and have a hot all the time then hot on accessory with a couple of data lines to the head unit?
